I think you misunderstood what I was saying. I have no idea if it's possible to get 500 cycles using an M36 at high loads. In your 8p configuration , I would bet that it will based on testing posted here, if your maximum current drain is less than 30 amps total . It seems more likely the M29 will fit that role better though. That's more for someone like Doc/Flippy/Padja to say. What I meant was, by the time you wear down a high discharge cell , "most" people would be ready to upgrade to a newer cell or chemistry , whichever. If you can get 3 years use out of a cell that can handle full throttle smashing with little sag, it makes more sense to go that route than to build a monster sized pack so you can keep it for 1000 charges, in which it will die of old age long before it dies from charge/discharge cycles. This point of view is only from someone that rides recreationally rather than for transportation every day.
and that in itself makes such a test most unlikely.
I will start with the answer that there is no good solution. One way or another you will be blamed that you chose the other way. Not only by the community but even yourself. At this settings (70% SoC window with ca 0.3-0.4C charge and 0.7-0.9 discharge rate) you should expect at least 1500+ cycles for good quality cells (by my standards) before they reach the EoL. Now it is clear that PF does not make it and GA will be on the border line at best (particularly because of DCIR rise). There is always a dilemma if you prematurely break the test and then you decided to continue some months or even years later, if this is good for methodology. I am ending all of my tests at 1000 cycles. I only tested LG HG2 up to 3500 cycles for about two years at ca 80% SoC window (4.1V-2.5V, 0.5-1C) and "this beast just didn't want to die".
